A projection capture system includes a camera to capture images of objects in a capture space, and a projector to illuminate the objects in the capture space and to project images captured by the camera into a display space. The projector includes a flash mode for providing white light for illuminating the objects in the capture space. The system includes a controller to adjust drive settings to LEDs of the projector to achieve a predetermined white point during the flash mode.

Examples disclosed herein relate to detecting misalignment of a touch sensitive mat Examples include detecting corners of the touch sensitive mat, determining a set of reference corners, performing a comparison of the detected corners of the mat with the set of reference corners, and determining a level of misalignment based on the comparison.

A processing device generates a marker image to use as a reference for correcting a shape of a projection image projected on a projection surface from a projector, takes a taken image of the projection surface using the imaging device from an imaging position different from an observation position from which the projection surface is observed, generates a parameter for reducing a distortion of the projection image based on the marker image included in the taken image, displays an area image representing a range wherein projection can be performed on the projection surface on the display device, disposes a video content at an indicating position in the area image with an input to the input device, generates an original image including the video content, and corrects the original image thereby generating an input image for input to a projector configured to project the projection image.

According to an illustrative embodiment, an information processing apparatus is provided. The apparatus is used for processing a first image projected toward a target. The apparatus includes a processing unit for detecting that an object exists between a projector unit and the target, wherein when an object exists between the projector unit and the target, the apparatus determines an area of the object and generates a modified first image, based on the area of the object, for projection toward the target.

The present application discloses systems and methods for a virtual input device. In one example, the virtual input device includes a projector and a camera. The projector projects a pattern onto a surface. The camera captures images that can be interpreted by a processor to determine actions. The projector may be mounted on an arm of a pair of eyeglasses and the camera may be mounted on an opposite arm of the eyeglasses. A pattern for a virtual input device can be projected onto a “display hand” of a user, and the camera may be able to detect when the user uses an opposite hand to select items of the virtual input device. In another example, the camera may detect when the display hand is moving and interpret display hand movements as inputs to the virtual input device, and/or realign the projection onto the moving display hand.

A projection apparatus and a projection method are provided. The projection apparatus includes a projection device, a capturing image device, and a processing device. The capturing image device is configured to obtain an environmental image. The processing device is coupled to the projection device and the capturing image device. The processing device is configured to analyze the environmental image to provide at least one effective projection region. The processing device selects one of the at least one effective projection regions as a target projection region. The projection device is configured to project a projection image to the target projection region.

Systems and methods are disclosed for using a wearable apparatus with overhead projection. In one implementation, a wearable apparatus may include an image sensor configured to capture a plurality of images from an environment of a user; a light projector; and at least one processor. The processor may be programmed to receive at least one image of the plurality of images; identify an item of information based on the at least one image; select a surface located within a field of view of the user; render the item of information into an informational image; and cause the projector to project the informational image onto the surface.

An electronic device includes a lens system. The lens system includes three lens elements, which are, in order from an outer side to an inner side: a first lens element, a second lens element and a third lens element. The first lens element with positive refractive power has an outer-side surface being convex in a paraxial region thereof. The second lens element has negative refractive power. The third lens element has positive refractive power.
